Abstract
A light deflector for deflecting light inputted through an optical fiber to switch a plurality of cross-connected optical fibers for optical communication. The light deflector is composed of a mirror for deflecting the inputted light, a supporting member for connecting with the mirror by at least one edge thereof, and a frame portion for holding the other edge of the supporting member. The supporting member is composed of a driving member incorporated thereof for transforming convex-concave by supplying an impressed voltage of zero and over values having inverted polarity in relation to initial condition, to make the mirror incline to desirable direction.

A light deflector for deflecting light to switch a plurality of cross-connected optical fibers for optical communication, comprising:
- a mirror for deflecting light input through the plurality of cross-connected optical fibers by sloping at the center thereof;
- a supporting member for holding the mirror in the same plane, wherein the supporting member is connected with the mirror at least one edge thereof;
- a frame portion for holding another edge of the supporting member;
- and
- a driving member incorporated in the supporting member for inclining the supporting member by transforming convex-concave to make the mirror sloping to desirable direction.
A method for driving a light deflector for use in switching a plurality of cross-connected optical fibers for optical communication, comprising:
- a mirror for deflecting light input through the plurality of cross-connected optical fibers by sloping at the center thereof;
- a supporting member for holding the mirror in the same plane, wherein the supporting member is connected with the mirror at least one edge thereof;
- a frame portion for holding another edge of the supporting member;
- and
- a driving member incorporated in the supporting member for inclining the supporting member by transforming convex-concave to make the mirror sloping to desirable direction,
- the method comprising steps of:
- holding the mirror for light deflection by the supporting member being connected with the mirror at least one edge thereof and the other edge with a frame portion;
- driving the driving member incorporated in the supporting member by supplying an impressed voltage to make the driving member transforming convex-concave to slope the mirror, wherein the impressed voltage is having zero and over values of inverted polarity compared to initial condition;
- and
- deflecting an input light through the optical fiber by the sloping of the mirror to a desirable direction.
